Abstract
A vent valve apparatus () for use with a system for supplying breathable gas pressurised above atmospheric pressure to a human or animal. The apparatus () includes a gas washout vent (), a vent valve () adapted to progressively restrict the flow area of the washout vent (), and a pressure sensitive vent valve control means (). The control means is adapted to progressively cause the vent valve () to restrict the flow area of the gas washout vent () in response to increases in the pressure of the gas supply, thereby substantially regulating the volumetric flow of gas and/or COgas through the washout vent () over a range of gas supply pressures.
